The output voltage is well over 30kV before breakdown of the spark gap occurs. Pushing it to higher voltages causes breakdown of the plastic casing, a phenomena it survived for well over a half an hour before I noticed the small purple streamers pouring out the bottom and onto my bench.

lest we forget the GMHEICSLR..... 11 inches and more!
